Product Description

D4 Automatic Transmission Fluid is a fully-synthetic product designed with superior low-temperature properties compared to a Dexron III fluid, and the improved shear-stability requirements which is part of the Mercon V specifications. D4 Automatic Transmission Fluid also provides a GL-4 level of gear protection, making it a superior product for transmissions and transaxles.
